VENTILATING-SCREEN.

To all whom it may concern:

Be it known that 1, Ann CLARENCE HOUGH, a citizen of the United States,and resident of J anesville. county of Rock, State of Wisconsin, haveinvented an Improve ment in Ventilating-Screens,-of which the followingdescription, in connection with the accompanying drawings, is aspecifica tion, like letters on the drawings representing like parts.

The present application relates to a modified form of my ventilatingscreen invention, as described and claimed broadly in my Patent No.1,218,556, issued March 6, 1917. The'present application is a divisionalof my pending application Serial No. 147 ,7 90, filed February 10, 1917,in which pending application I have elected to claim one form of myventilating screen construction. In the present divisional application Ihave elected to describe, illustrate and claim the form of myventilating screen construction which includes a combined spacing andwarp binding element between the slats constituting the ventilatingportion of my screen. While I prefer to construct a woven screen havinga nonventilating portion in combination with a ventilating portion orportions therewith, it will be readily understood that I may con structa screen embodying the present invention comprising exclusively aventilating construction. One of the important ad vantages of the screenutilizing a combined spacing and warp binding element consists in theease and facility with which such a screen may be built; in the firm,secure and permanent manner in which each slat is held, irrespective ofthe spacing therefrom to adjacent slats; and in the further importantfeature of enabling a variation in spacing to be made wherever desired.

Further features of the invention, details of construction, and novelcombinations of parts will be hereinafter more fully pointed out andclaimed.

Referring to the drawing illustrating a preferred embodiment of theinvention,

Figure 1 is a fragmentary view of a ventilating screen embodying theinvention;

Fig. 2 is a cross sectional view on the line 2 of Fig. 1.

Fig. 3 is an enlarged detail between adjacent slats, and the combinedspacing and Warp binding device, shown in cross section.

Divided and this application filed June 8,

Serial No. 173,631.

Fig. 4 is a cross sectional view of a modification.

As shown in the drawing, Fig. 1 comprises a portion of a ventilatingscreen hav ing a non-ventilating portion, consisting in the relativelybroad slats 1, 2, 3 and -1, closely woven by pairs of warp cords orstrands, 5, 6, 5, 6, which may be of any number and constituting anydesired proportional part of the screen, together with a ventilatingsection. This ventilating portion comprises a plurality of slats,preferably narrower than the slats constituting the non-ventilatingportion, which slats may be variously spaced and are here shown, for thesake of example, as a set of slats 7, S, 9 and 10, being spacedsubstantially equidistant from each other and slats l1 and 12 showing agreater spacing.

It will be understood that in a woven screen it is necessary to have thewarp cords or strands tightly interlaced about the slats in order toprevent the slats from becoming loose and working endwise. This has beenone of the diliiculties to be overcome and I accomplish this purpose inmy pres ent form of ventilating screen by providing combinedslat-spacing and warp cord bind ing elements as indicated at 13, 13.These elements may be of any desired length, such for example as thoseillustrated at 14;, giv-- ing greater spacing, and they hold the slatsspaced in their predetermined position while tightly binding or clampingthe warp cords thereabout. These spacing and clamping elements may be,also, of any desirable ma terial, and may be either small tubularmembers, or split tubular members, the latter being clamped about thewarp strands firmly binding them in position during the manufacture ofthe screen. Fig. 3 clearly illustrates the binding and spacing featureof such elements. I find that tubular strips of celluloid, cut intosuitable lengths and split,are capable of advantageous use for theseelements. Also similar metallic elements may be utilized, and clampedinto position as each successive slat is incorporated in the screen. Inusing celluloid or the like plastic material, the element can be appliedwhile in a plastic state, and thus more firmly and solidly unite andhold the warp strands and space the slats from each other, a suitabletool serving to apply and force the material while plastic into shape.

I have shown at and'21 the usual reinforcing-y strips about the topmostslat 22, and it will be understood that such reinforcing strips may beapplied at different. places throughout the length of the screen,-

curely and permanently binding the spaced slats in their position.

In the modification illustrated in Fig. 4, I have shown a furtheradvantage incident to my type of combined spacing and clamping device.This consists in making a ventilated screen, or a. ventilated portion ina screen, without interlacing the warp cords about the slats, but byrelying upon the clamping devices to secure the same. Referring to Fig.1, the slats 30 and 31 are secured by thewarp cords 32 and 33 runningalongside said slats parallel with each other and on the: same side,being engaged, clasped and clamped by the sleeves 35, 35, about thecords, as shown. It will be understood that in view of this modificationI do not intend that the term woven screen should be lim ited toaweaving of the warp strands interlaced about the slats, but may applyequally to the construction illustrated in Fig. 4. This arrangement ofhaving the warp cords running parallel or on the same side of the slats,maybe utilized only 'for the ventilating section, if desired, and theninterlaced forwardly and backwardly or to and fro about the remainingslats in the non-ventilating section.

My invention is further described and de fined in the form of claims asfollows:

1. A woven screen of the kind described, comprising a plurality oftransverse slats held together by woven warp strands interlaced over thefront-and bacle of alternate slats, in combination with a combinedspacing and strand holding element engaging the warp strands betweenadjacent slats.

2. A woven screen of the kind described, comprising. a ventilatingportion and a nonventilating portion, said ventilating portionconsisting in a plurality of transverse slats held together by wovenwarp strands interlaced over the front and back of alternate slats, incombination with a combined spacing and strand holding element betweeneach slat.

3. A wovenscreen of the kind described, comprising aplurality ofventilating portions and a non-ventilating portion, each ventilatingportion consisting in a plurality oftransverse slats held together bywoven warp strands interlaced over the front and back of alternateslats, in combination with a combined spacing and strand holdingele mentbetween each slat.

4. A woven screen of the kind described, comprising a plurality of"transverse slats spaced from each other atvarying distances, and beingheld tightly together by woven warp strands interlaced over the frontand back of alternateslats, in combination with combined spacing and.str'and clamping sleeves, the length of said sleeves determin}v ing thespacing of adj acentslat's;-

5.'A woven screenof the kind described, comprising a ventilating portionand non ventilating portion, said 'nonventilating portion consisting inslats held closely together by woven warp. strands interlacedtliereab'out, said ventilating portion having the slats woven fartherapart'than the nonventilating section, andso woven by said warp strandsas to permitthe said ventilating section slats to be spaced from eachother and from the end slat of'the non-ventilating portion, incombination'with means engag ing the warp strands between each of'theslats in said ventilating portion to hold'said warp strands tightly inenga'gementwith, and spaced from, adjacent slats. 7 j

6. In a woven screen, a non-ventilating, closely woven portion,comprising a plural ity of transverse slats held" together by woven warpstrands, and a" ventilatingportion, comprising a'plurality of transverseslats held together with the warps running parallel, and combined warpengaging andslat spacing devices, claspingsaidwa rp strands between thespaced slats.

7. In a woven screen, a non-ventilating, closely woven portion,comprising a plurality of transverse slats held. together by woven warpstrands, interlaced overthe front and back of alternate slats, incombination with a ventilating portion compris ing a plurality oftransverse slats with'the woven warp strands non-interlaced, a combinedspacing and strand holding element between each of said spaced slatsencompassing and locking said warp cords tightly about adjacent spacedslats.

In testimony whereof, Iha've signed my name to this specification, inthe'presence' of two subscribing witnesses.
